23	DC Link Low Voltage
25	AC Low/High Voltage
26	DC Comp Position Error (not providing rotation – locking)
27	PSC Fault – Current to inverter compressor between AC and DC converter is too high
28	Inverter Compressor DC voltage is too high
29	Comp Phase Over-current – Inverter compressor amperage is too high
31	Current-to-current transformer (CT) thermistor is too low
32	Inverter Compressor Discharge pipe overheat
34	High-pressure sensor high
35	Low-pressure sensor low
36/38	Refrigerant Leak detection
37	Exceed the compression ration limit
40	CT sensor error – Thermistor is disconnected or shorted out

Other LG AC Error Codes:

Error Code	Possible Cause	Solution
Code appears in the display. F1,F2 or F3	Air conditioner is in FAN mode and the number shown is the set fan speed.	This is normal. The air conditioner is working properly.
FL	The water collection tank is full.	Empty the water collection tank.
CH01	Short or open circuit in the indoor air thermistor.	Unplug the air conditioner and contact your authorized LG service center.
